I use "gaming glasses" from Amazon. They filter out blue light and reduce eye strain significantly - they're especially useful in situations where you don't have control over the lights - e.g. in a classroom or at a conference. Some of you may already know about the "f.lux" app for computers that changes the color temperature of your display when the sun goes down to make it more "red". This is also easier on the eyes. The "Twilight" app on Android devices is also helpful. I believe Apple has something called "Night Shift" that serves the same purpose. If you use Google Chrome to browse, there's an extension called "Dark Reader" that reverses the color scheme on webpages so that the background is black and text white. The most obvious, and easy tip to implement is: reduce brightness on your monitor/phone. Wish you all the best, Happy to answer questions!
